EYEGLASS-MOUNTING.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed Database, 1909. Serial No. 535,543.

To all whom it may concern:

Be it known that I, LEO F. Aim, of the city of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyeglass Mountings; and I do hereby declare the following to be a full, clear, and exact descrip tion of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-nu merals marked thereon.

My present invention relates to eyeglass mountings and more particularly to the type in which the guards are positioned or moved toward the nose by resilient means, such as springs, and are moved away from the nose by operating portions, such as finger pieces, the object of this invention being to pro-.

vide an inconspicuous construction which is.

' specification.

In the drawings: Figure 1 shows, in enlarged elevation, an eyeglass mountlng constructed in accordance with the present improvements, one of the guards and its spring being removed; Fig. 2 is a top plan View of the same parts; Fig. 3 is a bottom plan view with a portion of the remaining guard broken away; Fig. 4 is a central transverse section through the mounting.

In the embodimentof the invention here in shown the lenses A are connected by a preferably in approximately the plane of support which preferably comprises an arched or bridged portion 1 for straddling the nose, lens attaching devices or mounts 2 for securing the lenses A and connecting portions 3 between the bridging portion and the lens attaching devices. The connecting portions are in this instance in the form of horizontal loops of pliable material arranged in the rear of the plane of the lenses and permitting the adjustment of the lenses relatively to the bridging ortion for different pupilary distances. I

p n order to support the guards, brackets 4 are preferably extended from the bridging portion 1 and lie between the ends of the latter and the proximate lens attaching devices, in advance of the adjustable or liable loops 3, the upper surfaces of the brackets forming horizontal seats 5 for the nose guards, and having bearings or pivots 6 extending upwardly therefrom, with heads 7t at their upper ends to codperate wit-h the upper surface of the guards. Each uard, in this instance, is 'formed'fro'm a smgle'piece of flat stock and embodies a lever portion 8 provided at its forward end with an outwardly extending 'fingerpiece 9 connected thereto by downward or vertical bend 10, and also provided at its rear end with a nose engaglng member 14 preferably having upper and lower nose engaging pads or surfaces of any suitable or desired type. The particular form of nose engaglng member and its formation with respect to the guard lever, and their connection constitutes the subject matter of a divisional application Serial No. 709,208,

' filed July 13, 1912, and need therefore not be described herein. Each guard turns above the support upon its bearing or pivot 6, the lever 8 being provided in one edge with a laterally opening bearing recess 15 permitting the'guard to. be attached to or separated from the mounting by a lateral movement, and in orderto strengthen the lever in proximity to the recess the opposite opposite said recess. The springs for posis tioning the guards 1n this lnstance, are lo- :cated upon the under side of the support and may each embody a coiled portion 17 'ofiset to one side, preferably the rear side of the turning axis of the guard, and having an end 18 extending forwardly and entering a securing device in the present form of a socket 19 horizontally arranged the lenses on the under side of the support but facing or opening transversely of said plane; the other end of the spring being'in the form of a forwardly extending arm engaging the guard on the other side or edge of said lever is bent upwardly to pro- ,vide a longitudinally extending flange 16.

nose, the finger pieces 9 are pressed toward springs inwardly out of the eyes 21 when the levers may be moved inwardly from beneath the heads or overhanging portions 7.. The springs remain on the mountings when the guards are removed and may be removed; therefrom by withdrawing the ends 18 from the ckets 19. 7

An eyeglass mounting constructed in accordance with this invention is inconspicuous when upon the wearer. The springs I are so located that only small portions thereof are'visible from the front or top of the mounting, while they are, at the same time, s of such length as to give sufficient pressure upon the. nose of the wearer. The'connec tion of the springs to the mounting permits I laid.

the ready disconnection or attachment of the parts without the useof separate fastening devices that are liableto become lost or mis- In the claims: a

1. In an eyeglass mounting, the combination with a support, a pivot and a finger piece guard lever mounted to swing thereon and to extend from. front to rear of the support, of a spring for positioning the guard embodying two arms extending in substantially parallel relation transversely of the plane of the lenses and'connected together by a portion located on one side only of the pivotal axis, permitting the removal of the spring m a direction transverse to the said axis and to the pivot, saidj 'spring arms having their free ends detachably connected to the guard and support respectively, the connection with the guard being at a point on the opposite side of the pivotal axes thereof.

2. An eyeglass mounting comprising a support for the lenses, a guard mounted to swing on one side of the support, a spring securing device arranged on the other side of the support in the plane of the lenses, and a spring for the guard comprising an end secured by said device, a coil arranged to one side of the turning axis of the guard and an arm extending to the other side of the turning axis of'theguard and cooperating with the latter.

side of the support, and a spring comprising 'anendfitted in the socket, a coil on one side .of'the turning axis of the guard, and an arm "extending to the other side of the turning axis and secured to the guard. 1

5. An eyeglass mounting comprising a support for the lenses, a nose guard arranged above the support, cooperative bearing mem here on the guard and the support, separable by an inward movement of the guard, a socket arranged horizontally on the under side of the support, with its axis transverse to the plane of the lenses, and a spring for the guard comprising an end secured in the socket, a coiled portion in the rear, and a spring arm cooperating with the guard forwardly of the turning axis of the latter, and acting in a direction to hold the bearing members in engagement.

6. In an eyeglass mounting, the combination with a support, a pivot and a guard lever mounted to swing on the support, of a spring for positioning the guard having one end acting against the latter and the other against the support and provided with an intermediate loop or'coil arranged independently of the pivot to one side of the pivotal axis of the lever and means for securing one end of the spring to one of said first mentioned members comprising a box or socket on one part located to one side of-the loop or coil but substantially in the same plane extends. v

7 An eyeglass mounting comprising a support for the-lenses, a nose guard mounted to swing above the support, having a lever turned downwardly in front of the support, an eye arranged on the rear face of the downwardly turned portion, and a spring therewith into which socket the other part for the guard having a forwardly extending arm engaging said eye.
